bug in gnu 'comm' v2.0e

[mykle]

hi.  i'm not able to figure out from the web whether there is
a later version of GNU textutils than 2.0e ... if so, please 
point me at it and i'll test again.

i am including three files: f1, f2 and comm_out .
f1 and f2 are sorted lists of six-digit numbers.
f3 is the result of this command:

        comm f1 f2 > comm_out

... as executed on a RedHat 7.0 SMP (plus updates) 
dual-pentium system.  i've reproduced the same bug
on a RedHat 6.0 uniprocessor AMD system running 
GNU textutils v1.22

the bug: certain numbers appear in both column 2
(unique to second file) and column 3 (common to both files).
for instance, '139683' .

please let me know if you're able to reproduce the
bug, and anything else i can do to help.

thanks,
